This time, the PNG ( Papua New Guinea) Stadium canopy Membrane Structure Engineering is the embodiment of our company's strength. This project uses PVDF membrane, with a total construction area of 4800 square meters. As this is a roof membrane project, the construction difficulty is obviously increased.  At the same time, in order to the football match start as soon as possible, the customer asked us to complete the project in the shortest construction period, so it took only 20 days to complete the project with the joint efforts of the designers, engineers and site construction personnel of Sigma group. The following is a picture of the project.
